California Water Service Continues Main Replacement Initiative In Bear Gulch District

MENLO PARK, Calif.—As part of its proactive, systematic main replacement program to replace aging pipes and provide reliable water service to its Bear Gulch District customers, California Water Service (Cal Water) recently completed a main installation project in Woodside and began a new project in San Mateo County.

In Woodside, crews installed 2,240 feet of 6-inch ductile iron pipes in the area around Old La Honda Road and Martinez Road, which will increase firefighting capabilities and water flow to customers. The new main replaces 1- and 4-inch mains that were installed in 1944.

The new project in the San Mateo County area of Portola Valley includes the replacement of more than 3,000 feet of water mains along Los Trancos Road and surrounding streets. The new 6-inch PVC pipes will augment water flow, prevent leaks, enhance fire protection, and improve the overall water reliability of the system.

Installation of the new mains will take place Monday through Friday between 8 a.m. and 4 p.m. The project is expected to be completed by October 20, 2017.

"Our main replacement program emphasizes our priority to providing high-quality, reliable water service to our customers and increased fire protection for generations to come," said District Manager Dawn Smithson. "Both of these projects help us achieve our goal of delivering quality, service, and value to our communities."

Cal Water serves approximately 18,900 service connections in Portola Valley, Woodside, Atherton, and portions of Menlo Park, Redwood City, and San Mateo County and about 2 million people through 480,300 service connections in California. Additional information may be obtained online at
